_D_e_s_c_r_i_p_t_i_o_n:

     'autoload' creates a promise-to-evaluate 'autoloader' and stores
     it with name 'name' in '.AutoloadEnv' environment.  When R
     attempts to evaluate 'name', 'autoloader' is run, the package is
     loaded and 'name' is re-evaluated in the new package's
     environment.  The result is that R behaves as if 'file' was loaded
     but it does not occupy memory.
